Simple ... ask him!! If he hem-haws around with an answer, chances are it may not be the truth. Truthful answers are always the quickest responses.
Find out if he really is lying. If he is, find out if he has a good reason. Men's minds don't work the same as women's. to him, lying may seem like the logical way to solve a problem. Or, you could just dump him.
NO if he was a lying boyfriend that's not going to go away
He probably hasn't lied to you, but since your dreaming about it it is probably a fear to have your boyfriend lying to you.
you ask your boyfriend if that is true
Come clean or you will have to compound it any losses will be greater if they find out on their own.
ask him!
Prove to him that you aren't.

It depends on your circumstance! Lying is lying and no matter how you look at it's wrong! He probably lied to impress you, keep that in mind, in the end he's still your boyfriend!
Get addicted to drugs!!!! It works, trust me!
